Problems solved by technology

[0010] However, the existing magnetic gear 10 cannot concentrate the magnetic flux on the air gap between the outer rotor 12 and the pole piece module 13 and the air gap between the inner rotor 11 and the pole piece module 13 due to the limitation of the shape of the pole pieces 13a. , so there are problems of poor torque transmission and large torque ripple

Abstract

The present invention relates to a magnetic gear having a pole piece for improving transmission torque characteristics, more specifically, to improve the shape of a pole piece located between an inner rotor and an outer rotor, And to a magnetic piece having a pole piece for improving transmission torque characteristics capable of reducing torque ripple.

Description

technical field [0001] The present invention relates to a magnetic gear having pole pieces for improving transmission torque characteristics, and more particularly, to a magnetic gear for concentrating magnetic flux to an air gap by improving the form of pole pieces located between an inner rotor and an outer rotor , which can improve the transmission torque and reduce the torque ripple magnetic gear with a pole piece for improving the transmission torque characteristics. Background technique [0002] Magnetic gear is a non-contact gear device that uses magnetic force to transmit power in a non-contact manner. Compared with gears that transmit power through physical contact, it is safer due to less noise and vibration, no need for lubricating oil or maintenance inspection, and no mechanical friction. Due to its high performance and durability, research on magnetic gears has been active recently. [0003] Also, magnetic gears can reduce energy loss, enable high-efficiency dr...
